LAPACK Compared with LINPACK and EISPACK</A>
</H1>

<P>
LAPACK has been designed to supersede LINPACK&nbsp;[<A
 HREF="node151.html#dongarra79">38</A>]<A NAME="759"></A>
and EISPACK&nbsp;[<A
 HREF="node151.html#Smith76">92</A>,<A
 HREF="node151.html#Garbow77">54</A>]<A NAME="761"></A>, principally by restructuring the software to achieve much greater efficiency, where possible, on modern
high-performance computers; also by adding extra functionality,
by using some new or improved algorithms, and
by integrating the two sets
of algorithms into a unified package.

<P>
Appendix&nbsp;<A HREF="node146.html#chaplineis">D</A> lists the LAPACK counterparts of LINPACK
and EISPACK routines. Not all the facilities of LINPACK and EISPACK are
covered by Release 3.0 of LAPACK.
